Description
Technical field
The present invention relates to a kind of corrosion inhibiter and preparation method thereof, be specifically related to a kind of imidazoline quaternary ammonium salt oil well acidation inhibition
Agent and preparation method thereof.
Background technology
Since the seventies, probing that China Petroleum learning overseas is advanced and DP technology new technique, crude output by
Year significantly rises, and production development is very fast, carries out fracture acidizing as used big acid to measure high salt concentration acid solution, and steady output of oilwell increases production
Effect is the most notable.Although acidification of oil gas well operation adds oil recovery yield, but the acid solution used in acidization is to pipeline
Serious corrosion is all produced with equipment.Solving the most economical effective method of this difficult problem is exactly interpolation corrosion inhibiter in acidifying solution.
The appearance of acidification of oil gas well corrosion inhibiter solves a difficult problem for Oil/gas Well equipment corrosion just, just makes acidification of oil gas well technology obtain
Extensively application.On existing market, the Imidazoline Quatemary-ammonium-salt Corrosion Inhibitor for oil well acidation still suffers from undesirable the lacking of corrosion inhibition
Point, greatly limit its range of application.
